This study showed the dissemination of highly homologous influenza virus variants among inpatients and HCWs within a short period, as a result of nosocomial transmission. These strains were also similar to influenza strains that were circulating in the community.

The levels of IgG determined by ELISA may have limited relevance in human immunodeficiency virus (HIV)-infected adults because of nonfunctional antibodies. 58HIV-1-infected and 29 HIV-uninfected Ugandan adults were immunized with conjugate vaccine (CV) followed by polysaccharide vaccine (PV) after a two-month interval, and the opsonophagocytic killing (OPK) titers against serotype 4 or 14 pneumococcal strains as well as the levels of serotype-specific IgG in sera were determined.Significant increases were found in the OPK titers and IgG levels for both serotypes after CV vaccination irrespective of HIV status. Increases in IgG levels and OPK titers were largely dependent on the CD4 + cell counts, except for increases in the IgG levels for serotype 4. The proportions with serum OPK titer equal to or greater than 8 were 0-4.3% for serotype 4 and 26.7-42.9% for serotype 14 before vaccination, but the proportions increased up to 43.3-86.2% for serotype 4 and 63.3-96.6% for serotype 14 in all three groups 2 months after CV vaccination. The serum OPK titers remained at levels higher than the pre-vaccination level for at least 8 months after CV vaccination. A

A 63-year-old man developed a pleural effusion with marked eosinophilia, which was more prominent in the pleural fluid than in the peripheral blood. The pleural effusion spontaneously disappeared 7 days after admission. A multiple dot enzyme-linked immunosorbent assay for anisakiasis was strongly positive for both the serum and pleural fluid. The serum IgG titre for Anisakis simplex gradually decreased over 7 months. It is suspected that Anisakis larvae can penetrate the alimentary canal, and then migrate into the pleural cavity through the diaphragm. Screening with a serological test is useful in the diagnosis of this condition; human pulmonary anisakiasis.
